Description:
ISS X-Force has reported a vulnerability in the NSS library, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error within the parsing of records during SSLv2 connection negotiation. This can be exploited to cause a heap-based buffer overflow by sending a specially crafted client hello message with an overly long record.
Successful exploitation allows execution of arbitrary code with the privileges of an application linked to the vulnerable library.
Solution:
An updated version of the NSS library is available:
ftp://ftp.mozilla.org/pub/mozilla.org/security/nss/releases/NSS_3_9_2_RTM
Provided and/or discovered by:
Mark Dowd, ISS X-Force.
Changelog:
2004-09-06: Added CVE reference.
